Specification of Letters Patent.

Patented sept. i5, 190e.

To all whom' it Imay concern: i

Beit known that I, JAiiiis A. llfiiirn, a citizen oi the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have inwindow screen which may be cheaply con-v structed chiefly or wholly of metal, thereby materially enhancing its efficiency and durability; which shall be comparatively light in weight, simple in its details of, construc-` tion, and convenient in its application to practical purposes; and which shall possessy certain ivcll-dclined advantages` over prior analogous devices. l I

The invention consists in the novel fet/hm binations, parts and details o'l" constrilrtion the tie-rail made .use

whereby, together with the novel disposition and relative arrangement of said parts, the attainment of the foregoing object rendered practicable, all of which will be hereinafter more speciiically described and set forth in the appended claims.

The invention is clearly illustrated. in the accompanying drawings, wherein like ret eience-numerals denote corresponding parts throughout the several views, and as to the latter: Figure 1 is a tace view ot a window screen constructed in accordance with my invention. Fig. 2 is a transverse section thereof, as along the line 1t-fr of Ilig. 1. Fig. 3 is an edge view ol saine; and Fig. et is a detail cross-sectional view ot one ol the tie-rails inadeuse oi", Fg. 5 is a 'fragmentary i perspective view ot one corner of' the general frame structure showing the connection ol oi'- with the clamping ledge of the device.

In Oa general sense my p comprises opposite side-i" an end-rail, the said sidend'l boing cach, formed from a'rsingle strip of metal; aclampiiig tic-rail, connecting said sido-rails in opposition to said end-rail; and a segment of open-mesh l'abric, the latter secured marginally to said sido-rails, re-v risent invention connected by i i l spectively, and said end-rail,- and having its remaining" margin clamped and lieldfby` said tie-rail,` l Y It further comprises, in a general sense, a pair of inain `members constructed,` each, substantially as above specified', andfineans for holdingl said main'inenibers slidably together, whereby each may be adjusted relatively to the other.

In carrying out my invention, reference being had to the accompanying drawings, I provide opposing side-rails connected by an end-rail, each of which several rails is formed from .a single strip of sheet-metal, folded longitudinally, at 2, and returned some'- what substantially upon itself', thereby forining a tivo-fold clann'iing ledge 3, one of whose constituent members is extended outwardly in the plane of said ledge to forni a rear side member 4, while Ithe other is turned or bent forwardly substantially at right angles to said ledge to torni an inner edge-wall 5; thence turned outiinrdly, par# allel with the rear n'ioi'nber a, to 'loi'ni a ront side member 6; then. turned bacliivaidly to torni :in outeii edge-wall 7 and then turned inwardly and terminated in va stiltening strip S, :it the forward lirico ol 'the rear sidey meinbei" sl, the said ledge accordingly extending longitudinally along said rail at the inner side theicol, with its constituent meinbers integrally connected along their inner.

edges, and cach integrally connected along its outer edge with said rail proper, thc latter and said ledge being, accordingly formed of one and the saine material.; and said side-- rails and end-rails, respectively, being suit ably init-cred, and thereafter lusciied together in any approved and well known inanner, as by soldering at the points Q and l0.

It will be observed that when the side-rails and end-rail are thus assembled, the ledge 3 extends continuously along one of said siderails, the end-rail, and the opposite side-rail, thereby materially strengthening the traine structure thus l'oimcd; and upon said ledge ll dispose a segment `or sliccti ol' opcnincsii fabric," l l prclcrzibly constructed ot'- wii l same being prinnirily vtacked or` secured thereto,-atintervils lhercalong, by inea-ns of s `and end-rail' solder, or other appropriate holdingii'nediuni.

The lillet l2 serves to incite definitely insure the retention the llt:

form a h'ollow completed vstructure of such cross-sectional contour as 4to adapt it tofit into and'. filly withfair nicety the rabbet of the side-rails and end-rail aforenamed, -respectively, and substantially as illustrated in e drawings. The remaining marginof the fabric 11 is firmly held between the opposing elampin -members (Fig. 4) 13, 14of the tierail 15, t e'latter connecting and firmly; holdingthe ends of the respective side-rails and the twofold ledges thereof, opposite to the 'end-rail aforenamed, said tie-rail being sol- .dered or otherwise rmly conjoined' therewith.v f

, The tiei-rail1v5 is primarily formed-by longitudinally folding and returning a single strip of sheet-metal practically upon itself,

thereby forming the opposing clamping-meml bers 13, 14 thereof. j -members is inserted the adjacent margin of the fabric 11; and thereafter said tie-rail as -ax whole is subjected to a suitable sidepressure, by means of an appro riate die, or other'suitabledevice, whereby t e clampingmembers 13, 14, are simultaneously forced closely together and at the same time de- ,iiected sidewise in unison, thus causing themto firmly grasp and4 hold the' margin of the fabric 11 .inserted therebetween.

, Ordinarily, I purpose to provide a pair of mainscreen. members, each com rising parts formed, constructed and'assemb ed substanl'tially as` herein,described and illustrated in the drawings, the said main' members being slidably conjoined in such a manner that each l may be adjusted'relatively to theother for Widths.

the purpose ofA accommodating the adjust.

able device as a whole to openings of different In this' connection purposeA to make use of guide-clips, formed in any appropriate manner, and conjoined with the mam screen members 1n such a manner that those carried by either of sald mam screen members will take partially around the siderails, respectively, of the opposing screen membensubstantially as shown in the drawings. l Specifically, and as here shown,'each of said guide-clipsl is formed from a piece of sheet-metal, of suitable rigidity, and com prises a main portion 16, whose inner end is grasped by, and held between, the opposing members of the ledge3, from whence said i main portion projects outwardly between the rear side-member 4 and the'sti'fening strip 8 of the rail in conjunction with which it is used; thence turned substantially at right angles rearwardly of said rail, and projected along the outer edge of the adjacent rail of the opposing main screen member; and then l and returned somewhat, thereby Between these clampreturned substantially at right angles inwardly and terminating in a final portion 17, which projects inwardly along the front sidemember 6, at the outer side thereof.

It will be understood that the number of guide-clips. used in conjunction with each side-rail. of the respective main screen 'members, and likewise the arrangement thereof with respect to such rail, may be varied as may be found desirable in practice. However, when arranged substantially as herein shown and described, those carried by one of the main screen members will collide with those carried by the other main screen member, under sulieient relative adjustment of the respective main' screen members, and thus limit the adjustment of the latter in one direction, which is desirable.' On the other hand, relative adjustment of said main screen members in the op osite direction may be freely continued untiljeach is disengaged from the guideeclips of the other, and said main screen members may be taken apart or separated. By reversing this last named adjustment of the mam screen members, the same may be reassembled for service as an adjustable window screen,` as will also be l readily understood.

- It willbe seen that my improved window screen is particularly well adapted for the V.purposes for which it is intended; and further that the same may be modified to a consideriable extent, particularly as regards the means availed of for slidably holding 4the main screen members together, the general character of the open mesh fabric made use of', and'various details of the general construction, Without material departure from the spirit and principle of my invention.
